The Galileoscope is a high-quality, low-cost telescope kit developed by a team of leading astronomers, optical engineers, and science educators. No matter where you live, with this easy-to-assemble, 50-mm (2-inch) diameter, 25- to 50-power achromatic refractor, you can see the celestial wonders that Galileo Galilei first glimpsed 400 years ago and that still delight stargazers today. These include lunar craters and mountains, four moons circling Jupiter, the phases of Venus, Saturnís rings, and countless stars invisible to the unaided eye.

For optically slowing or completely stopping any object in motion, and for measuring the frequency of periodic motion. Consists of a black metal disk of 250mm diameter with 12 evenly spread radial slits extending to its edge. An axis hole for mounting a handle and a finger hole. Handle and mounting screws are included.

This lens set is comprised of the most important types of lenses. Optically true with ground glass edges.
Includes one of each: double convex, plano-convex, double concave, plano-concave, concavo-convex and convexo-concave, arranged in a velvet lined case. Diameter 50 mm

Easy and quick 4-Watt Ultraviolet light for mineralogists and forensic experts. Portable 6" UV lamp is also one of the most exciting devices for students who are doing an experiment with UV light. This portable light also comes with a white, super bright LED torch that makes it usable as a general-purpose light source. At home you can use it to reveal the hidden stains from pets (urine stains), oils and some bacteria.

For Demonstrating important principles of optics such as reflection by various shapes of mirrors, refraction through several types of lenses, total internal reflection and dispersion. The apparatus consists of a metallic disk about 30cm in diameter, graduated around the circumference in 360 degrees. A handle on the back can be used to rotate the disk in a vertical plane about a horizontal axis perpendicular to the plane and passing through the center of the disk.
